I am smiling today because the pigeons that have made a total and utter mess of my balcony appear to have gone away. That's the thanks I get for letting a couple of them nest here last year.
It was a total nightmare trying to persuade them that they were no longer welcome. I even bought an owl ornament and all they did was make more mess around it. It was only when I caught a few of them sleeping on the rafter above and gently prodded one on the tail with a rod that they all fluttered off in panic not to be seen again!
I can imagine them getting together with their bird-brained friends and telling each other "coo roo-c'too-coo" which in English means "don't got to that balcony again, it's not very comfortable".
